通信系统、通信设备及其控制方法 Communication system, a communication device and a control method

技术领域 FIELD

[0001] 本发明涉及一种通信系统、通信设备及其控制方法。 [0001] The present invention relates to a communication system, a communication device and a control method.背景技术 Background technique

[0002] USB(通用串行总线）是开发作为用于将外围装置连接到个人计算机的手段的传统技术。 [0002] USB (Universal Serial Bus) is developed as a means for connecting a peripheral device to a personal computer of the conventional art.个人计算机通常用作主机，而例如打印机、图像扫描仪等的外围设备用作装置。 Personal computers typically used as a host, such as a printer, image scanner or the like is used as a peripheral device means.

[0003] 然而，近年来，USB标准还用于相互连接其它消费装置，因此，个人计算机以外的装置也开始用作USB主机。 [0003] However, in recent years, USB standard also for other consumer devices connected to each other, and therefore, a device other than a personal computer as a USB host started.这种情况的例子有直接打印方案，其中数字静止照相机（DSC)和打印机通过USBl对1连接，并通过打印机将存储在数字静止照相机中的拍摄图像打印出来。 Examples of this are a direct printing scheme in which a digital still camera (DSC) and a printer connected by USBl of 1, and the captured image by the printer is stored in the digital still camera is printed out.在这种情况下，打印机用作主机，而数字静止照相机用作装置。 In this case, the printer as a host, and the digital still camera is used as means.

[0004] 通常而言，包括这种直接打印功能的打印机具有当用作装置并连接到个人计算机时使用的USB装置端口和当用作主机并连接到数字静止照相机时使用的USB主机端口两 [0004] Generally, such a direct printing function including a printer with a USB host port using two and when the apparatus is used as the device connected to the USB port of a personal computer used as a host, and when connected to the digital still camera and

者ο Who ο

[0005] 此外，近年来，使得可以进行无线USB通信的无线USB (wireless USB, WUSB)协议已经被标准化，因此，现在能够无线地实现曾经通过有线USB实现的通信。 [0005] Further, in recent years, such wireless USB communication may be wireless USB (wireless USB, WUSB) protocol has been standardized, and therefore, it was possible to achieve communication by wired USB wirelessly.

[0006] 使用WUSB系统使得可以实现无线直接打印。 [0006] using the WUSB system makes it possible to realize wireless direct printing.

[0007] 可以将WUSB功能直接集成在主机或装置内，并且也可以通过将WUSB适配器连接到已经配备有标准USB接口的装置来实现该WUSB功能。 [0007] WUSB functionality can be integrated directly in the host or device, and can also be connected to the WUSB adapter device has been equipped with a standard USB interface to achieve the WUSB functionality.

[0008] 此外，打印机可以设置有无线直接打印功能以及WUSB适配器功能。 [0008] Further, the printer may be provided with a wireless direct print function and WUSB adapter functionality.

[0009] 在下面的说明中，将设置有WUSB适配器功能和无线直接打印功能两者的打印机称为“多重控制站(multiple controlstation)，，。 [0009] In the following description, will be provided with both WUSB adapter functionality and wireless direct printing function of the printer is called "multiple control station (multiple controlstation) ,,.

[0010] 作为相关技术的例子，已经公开了一种用于将多个无线终端连接到单个USB装置的技术(专利文献1 ：日本特开2004-78359)。 [0010] Examples of the related art, a technique has been disclosed (Patent Document 1: Japanese Patent Laid-Open 2004-78359) for connecting a plurality of wireless terminals to a single USB device.

[0011] 作为相关技术的另一例子，存在一种设置有有线外部接口和无线外部接口两者的无线调制解调器（专利文献2 ：日本特开2003-8684)。 [0011] As another example of the related art, there is a wireless modem provided with a both wired external interface and a wireless external interface (Patent Document 2: Japanese Patent Laid-Open 2003-8684).

[0012] 此外，作为相关技术的又一例子，存在一种设置有用于打印来自无线终端的数据的功能的传真装置（专利文献3 ：日本特开2000-232681)。 [0012] Further, as still another example of the related art, there is a data for the print function from the wireless terminal facsimile apparatus (: Japanese Laid-Open 2000-232681 Patent Document 3) is provided.

[0013] 然而，关于多重控制站，可以考虑下面的问题。 [0013] However, with regard to multiple control stations, consider the following questions.

[0014] 首先，当在WUSB适配器操作和无线直接打印操作之间切换时，用户需要对多重控制站进行切换操作等。 [0014] First, when switching between WUSB adapter operations and wireless direct printing, the user needs to switch operation of the multiple control station.当使用有线USB系统进行直接打印时，用户不需要对打印机进行任何特定的操作。 When using a wired USB direct print system, the user does not require any particular printer operation.特别地，当与有线USB相比时，其中，打印机简单地通过经由线缆连接数字静止照相机切换为操作模式。 In particular, when compared to the wired USB, where the printer simply by switching the operation mode of the digital still camera via a cable connection.另一方面，由于使用无线USB的多重控制站需要通过切换操作等来明显地切换操作，因此上面的系统缺少便利性。 On the other hand, since the multiple control station using the wireless USB needs to be apparently the switching operation by the switching operation or the like, so the above system lacks convenience.

[0015] 其次，还可以考虑正在执行无线直接打印的同时停止适配器功能的情况。 [0015] Second, you can also consider executing wireless direct printing function while stopping the adapter case.这种情况会出现如下问题：在停止适配器功能期间，不能将其它的WUSB装置连接到个人计算机。 This occurs a problem: the adapter function during the stop, can not be connected to another personal computer, a WUSB device.

[0016] 关于相关技术，专利文献1中公开的技术选择多个无线装置，并将这些装置连接到单个USB主机，因此不能应用于具有多个USB主机的多重控制站。 [0016] For related art, Patent Document 1 discloses a technique of selecting a plurality of wireless devices, and these devices are connected to a single USB host, and therefore can not be applied to multi-station having a plurality of USB hosts.

[0017] 同时，专利文献2公开了根据与有线接口的连接的状态来切换无线调制解调器的操作模式的结构。 [0017] Meanwhile, Patent Document 2 discloses a configuration to switch the operation mode according to a state of a wireless modem connected to the wired interfaces.由于该原因，用户需要进行用于将装置连接到有线接口或从有线接口断开装置的操作，以便切换操作模式，从而导致系统缺少便利性。 For this reason, the user is required for connecting the device to the wired interface or a disconnect operation of the apparatus from the wired interface in order to switch the operation mode, causing the system lacks convenience.

[0018] 最后，根据专利文献3中公开的技术，打印和外部连接仅局限于单个无线终端，因此不能同时为存在的多个无线终端提供多个功能。 [0018] Finally, according to the technique disclosed in Patent Document 3, printing and external connections is limited to a single wireless terminal, and therefore can not provide multiple functions for multiple wireless terminals present.

具体实施方式 detailed description

[0032] 以下将参考附图详细说明用于执行本发明的优选实施例。 [0032] The following detailed description with reference to the accompanying drawings for carrying out a preferred embodiment of the present invention.

[0033] 第一实施例 [0033] First embodiment

[0034] 图1是示出根据本发明第一实施例的多重控制站的内部结构的示例的图。 [0034] FIG. 1 is a diagram illustrating an example of an internal configuration of the multiple control station of the first embodiment of the present invention.同时， 图2是示出根据本发明第一实施例的无线通信系统的结构的示例的图。 Meanwhile, FIG 2 is a diagram showing an example of configuration of a wireless communication system according to a first embodiment of the present invention.

[0035] 在图2中，具有打印功能的多重控制站201通过USB线缆23连接到个人计算机21，并作为无线USB(WUSB)适配器工作。 [0035] In FIG. 2, the multiple control station 201 has a printing function via the USB cable 23 is connected to the personal computer 21, and (the WUSB) adapter operates as a wireless USB.同时，多重控制站（打印机）201还可以使用无线直接打印53，来打印来自终端站（数字静止照相机）52的照片。 Meanwhile, the multiple control station (printer) 201 can also use wireless direct print 53, print photographs from a terminal station (digital still camera) 52.

[0036] 内部集线器83用作有线USB集线器。 [0036] The inner hub 83 is used as a wired USB hub.USB接口（I/F)单元106连接到内部集线器83，并用作有线USB接口。 A USB interface (I / F) unit 106 is connected to the internal hub 83, and functions as a wired USB interface.打印功能选择单元105选择USB接口单元106和无线直接打印功能单元103之一，并将所选择的单元连接到打印功能单元107。 Printing function selection unit 105 selects one of the USB interface unit 106 and a wireless direct print function unit 103, and the selected cell is connected to the print function unit 107.适配器功能单元102用作连接具有有线USB接口的装置的WUSB适配器。 Adapter function unit 102 is used as a connection means having a WUSB adapter to a wired USB interface.UWB(超宽带（ultra wide band))无线单元104通过天线发送和接收UWB无线信号。 UWB (Ultra Wideband (ultra wide band)) and the wireless unit 104 transmits the received UWB radio signal through an antenna.WUSB通信使用无线UWB作为其通信方案，从而无线地执行USB通信。 WUSB communication uses wireless UWB as its communication scheme, whereby USB communication performed wirelessly.

[0037] 无线直接打印功能单元103是用于通过WUSB无线链接执行直接打印的功能单元。 [0037] Wireless direct printing function unit 103 is a functional unit to perform direct printing by a WUSB wireless link.无线直接打印功能单元103还保持所使用的识别符，从而多重控制站201可以作为无线直接打印主机工作。 Wireless direct printing function unit 103 also holds an identifier used so that the multiple control station 201 can work as a wireless direct print host.下文中，将该识别符称为“第一主机识别符”。 Hereinafter, this identifier is called a "first host identifier."第一主机控制单元202使用该第一主机识别符，来根据WUSB主机功能执行无线协议处理。 First host control unit 202 uses this first host identifier to execute wireless protocol processing in accordance with the WUSB host function.

[0038] 同时，适配器功能单元102通过内部集线器83连接到个人计算机21，并从个人计算机21获取由个人计算机21所保持的主机识别符。 [0038] Meanwhile, the adapter function unit 102 through an internal hub 83 is connected to the personal computer 21, and acquires a host identifier held by the personal computer 21 from the personal computer 21.该主机识别符具有不同于第一主机识别符的值，并在下文中称为“第二主机识别符”。 This host identifier has a value different from the first host identifier, known as the "second host identifier" hereinafter.第二主机控制单元203使用该第二主机识别符，来根据WUSB主机功能执行无线协议处理。 The second host control unit 203 using the second host identifier to execute wireless protocol processing in accordance with the WUSB host function.

[0039] 主机仲裁单元204对由第一主机控制单元202和第二主机控制单元203相对于UffB无线单元104所执行的控制进行仲裁。 [0039] The host arbitration unit 204 by the first host control unit 202 and the second host control unit 203 with respect to the control unit 104 performs wireless UffB for arbitration.例如，如果第一主机控制单元202或第二主机控制单元203请求传输帧的无线传输，则主机仲裁单元204接收该传输帧，然后将其传送至UffB无线单元104。 For example, if the first host control unit 202 or the second host control unit 203 requests the wireless transmission of the transmission frame, the host arbitration unit 204 receives the transmission frame, and transmits it to the wireless unit 104 UffB.然后，作为UWB无线信号，UffB无线单元104从天线传输该传输帧。 Then, as a UWB wireless signal, Uffb wireless unit 104 transmits the transmission frame from the antenna.

[0040] 相反地，如果UWB无线单元104接收到无线帧，则主机仲裁单元204从UWB无线单元104接收该帧。 [0040] Conversely, if the UWB wireless unit 104 receiving the wireless frame, the host arbitration unit 204 receives the frame from the UWB wireless unit 104.然后，主机仲裁单元204分析帧的细节，并且如果帧是与无线直接打印有关的帧，则将该帧传送到第一主机控制单元202，或者如果帧是与个人计算机21有关的帧， 则将该帧传送到第二主机控制单元203。 Then, the host arbitration unit 204 analyzes details of the frame, and if the frame is a frame related to wireless direct printing, then the frame to the first host control unit 202, or if the frame is a frame related to the personal computer 21, will the frame is transmitted to the second host control unit 203.

[0041] 以这种方式，第一主机控制单元202和第二主机控制单元203可以通过主机仲裁单元204控制使用时分方案在无线信道上进行通信的UWB无线单元104。 [0041] In this manner, the first host control unit 202 and the second host control unit 204 controls 203 may use a time-division scheme through the host arbitration unit 104 for UWB wireless communication unit over a wireless channel.两个主机控制单元202和203可以被认为是在共享UWB无线单元104的同时独立地工作的两个主机。 Two host control units 202 and 203 may be considered as two hosts that operate independently while sharing the UWB wireless unit 104.

[0042] 注意，当构建图2中示出的无线通信系统时，用户在多重控制站201和个人计算机21之间执行配对处理，并且配置第二主机识别符。 [0042] Note that when constructing the wireless communication system shown in FIG. 2, the user performs pairing processing in the multiple control station 201 and between the personal computer 21, and the configuration of the second host identifier.类似地，用户还在多重控制站201和终端站52之间执行配对处理，从而配置数字静止照相机52，以使得第一主机识别符是与直接打印主机相对应的识别符，并且第二主机识别符是与无线USB适配器主机相对应的识别符。 Similarly, the user also performs the pairing process between the multiple control station 201 and the terminal station 52, configuring the digital still camera 52, so that the first host identifier is printed directly corresponding to the host identifier identifying the host and a second operator is the wireless USB adapter host corresponding to the identifier.

[0043] 接着，将参考图3和4说明多重控制站201响应于来自数字静止照相机52的请求切换到无线直接打印功能或个人计算机21适配器功能的处理。 [0043] Next, with reference to FIGS. 3 and 4 illustrate the multiple control station 201 in response to a request from the digital still camera 52 is switched to the direct print function of handling radio or a personal computer 21 adapter function.

[0044] 图3是示出当多重控制站201从数字静止照相机52接收到无线直接打印请求时所执行的操作序列的图。 [0044] FIG. 3 is a diagram illustrating the sequence of operations when the multiple control station 201 receives from the digital still camera 52 to the wireless direct print request performed.物理上而言，设置在多重控制站201内的第一主机控制单元202 和第二主机控制单元203通过主机仲裁单元204和UWB无线单元104与数字静止照相机52 进行通信。 First host control unit 202 and the second host control unit Physically, disposed within the multiple control station 201 communicate with hosts 203 and arbitration unit 204 and the UWB wireless unit 104, the digital still camera 52.然而，为了简便起见，在图3中仅示出了第一主机控制单元202/第二主机控制单元203与数字静止照相机52之间的帧的逻辑交换。 However, for simplicity, it is shown in FIG. 3 only the logical exchange of a first host control unit 202 / the second host control unit 203 and between the frame 52 of the digital still camera.

[0045] 首先，当启动多重控制站201时，第一主机控制单元202从无线直接打印功能单元103接收第一主机识别符，并以循环的方式重复发送包括第一主机识别符的第一广播帧。 [0045] First, when the multiple control station 201 starts, the first host control unit 202 wireless direct printing function 103 receives the first host identifier unit, and a cyclic manner from repeatedly transmitting a first broadcast comprises a first host identifier frame.另外，第二主机控制单元203以循环的方式重复发送包括通过上述配对处理配置的第二主机识别符的第二广播帧。 Further, the second host control unit 203 repeatedly transmits a cyclic manner comprises a second host identifier configured through the pairing process in the second broadcast frame.注意，在该时间点，打印功能选择单元105选择USB接口单元106，并将其逻辑连接到打印功能单元107。 Note that, at this time point, print function selection unit 105 selects the USB interface unit 106, and connected to the print function logic unit 107.换句话说，多重控制站201可以用作通过USB线缆23 连接到个人计算机21的外围装置，并执行打印操作。 In other words, the multiple control station 201 can be used as a connection via a USB cable 23 to the personal computer 21, a peripheral device, and the printing operation is performed.

[0046] 同时，数字静止照相机52交替地接收第一广播帧和第二广播帧，并检测包括在各广播帧中的第一和第二主机识别符。 [0046] Meanwhile, the digital still camera 52 receives the first broadcast frame and the second frame alternately broadcast, and detects a first and a second host comprising an identifier in the broadcast frame.这里，如果用户希望执行无线直接打印，他/她通过对数字静止照相机52进行按钮操作等来指定无线直接打印模式。 Here, if the user wishes to perform wireless direct printing, he / she specifies wireless direct printing mode button operation by the digital still camera 52.

[0047] 借此，数字静止照相机52选择基于通过上述配对处理进行的配置来指定无线直接打印作为主机的第一主机识别符。 [0047] Accordingly, the digital still camera 52 based on the configuration selection designated wireless pairing process carried out by the above-described direct printing as the host to the first host identifier.然后，作为对第一广播帧的响应，发送包括第一主机识别符的连接请求帧。 Then, as a response to the first broadcast frame, comprising a first host transmits a connection request frame identifier.

[0048] 同时，当多重控制站201接收到包括第一主机识别符的连接请求帧时，位于多重控制站201内的主机仲裁单元204从UWB无线单元104取得该连接请求帧。 [0048] Meanwhile, when the multiple control station 201 receives the first host identifier comprises a connection request frame, the host arbitration unit located within the multi-station 201,204 acquires the connection request frame from the UWB wireless unit 104.然后，主机仲裁单元204分析该帧的细节，并且如果分析的结果指示其中存在有第一主机识别符，则将该连接请求帧传送到第一主机控制单元202。 Then, the host arbitration unit 204 analyzes details of the frame, and wherein if the result of the analysis indicates the presence of the first host identifier, the connection request frame is transmitted to the first host control unit 202.

[0049] 此后，第一主机控制单元202基于WUSB主机协议，进行与数字静止照相机52的认证处理，并且最终完成了数字静止照相机52和多重控制站201之间的连接。 [0049] Thereafter, the first host control unit 202 based on the WUSB host protocol, authentication process with the digital still camera 52, and finally completed the connection between the digital still camera 52 and the multiple control station 201.然后，数字静止照相机52能够执行无线直接打印。 Then, the digital still camera 52 can perform wireless direct printing.

[0050] 接着，第一主机控制单元202通知连接检测单元205数字静止照相机52已经连接以进行无线直接打印操作。 [0050] Next, the first host control unit 202 notifies the connection detection unit 205 a digital still camera 52 has been connected for wireless direct printing operation.然后，连接检测单元205指示打印功能选择单元105断开迄今逻辑连接到打印功能单元107的USB接口单元106。 Then, the connection detection unit 205 instructs the printing function selection unit 105 to disconnect the logical connection date print function unit 107 of the USB interface unit 106.连接检测单元205进一步指示打印功能选择单元105将无线直接打印功能单元103连接到打印功能单元107。 Connection detection unit 205 further instructs the print function selection unit 105 to the print function unit 103 is connected to wireless direct printing function unit 107.借此，基于无线直接打印功能单元103的控制，将打印功能单元107连接到数字静止照相机52，从而使得能够打印来自数字静止照相机52的照片。 Accordingly, the control of the wireless direct print function unit 103, the print function unit 107 is connected to the digital still camera 52, so that the photographs can be printed from the digital still camera 52.

[0058] 接着，将参考图7说明根据从数字静止照相机52接收到的连接请求帧中存在的主机识别符来切换多重控制站201的功能单元的处理。 [0058] Next, will be described with reference to FIG. 7 handover processing function unit of the multiple control station 201 received from the digital still camera 52 to the connection request frame identifier present in the host.

[0059] 图7是示出根据本发明第一实施例的多重控制站201的控制过程的流程图。 [0059] FIG. 7 is a flowchart illustrating a control procedure of the multiple control station 201 of the first embodiment of the present invention.首先，在步骤S701中，第一主机控制单元202从无线直接打印功能单元103接收第一主机识别符，并发送包括该第一主机识别符的第一广播帧。 First, in step S701, the first host control unit 202 receives the first host identifier from the wireless direct printing function unit 103, and transmits the first broadcast frame comprises a first host identifier.经由主机仲裁单元204通过UWB无线单元104执行该发送。 Via the host arbitration unit 204 performs the transmission through UWB wireless unit 104.接着，在步骤S702中，第二主机控制单元203发送包括通过与个人计算机21执行的配对处理所配置的第二主机识别符的第二广播帧。 Next, in step S702, the second host control unit 203 transmits a second broadcast frame including a second host identifier configured through the pairing process executed with the personal computer 21.也经由主机仲裁单元204通过UWB无线单元104执行该发送。 Via the host arbitration unit 204 also performs the transmission through UWB wireless unit 104.

[0060] 此后，在步骤S703中，判断是否已经从数字静止照相机52接收到连接请求帧。 [0060] Thereafter, in step S703, it is determined whether it has received from the digital still camera 52 to the connection request frame.如果还未接收到连接请求帧，则过程返回到S701，并且重复上述广播帧发送。 If the connection request frame has not been received, the process returns to S701,, and repeat the broadcast frame transmission.然而，如果已经从数字静止照相机52接收到连接请求帧，则过程进入步骤S704，在步骤S704中，主机仲裁单元204判断连接请求帧中存在的识别符是第一主机识别符还是第二主机识别符。 However, if the request frame has been received from the digital still camera 52 to the connector, the process proceeds to step S704, in step S704, the host arbitration unit 204 determines the connection request frame identifier is present in the first or the second host identifier identifying the host symbol.如果判断结果表示该识别符是第一主机识别符，则过程进入步骤S705，在步骤S705中，主机仲裁单元204将连接请求帧传送至第一主机控制单元202。 If the determination result indicates that the identifier is the first host identifier, the process proceeds to step S705, the in step S705, the host arbitration unit 204 transmits the connection request frame to the first host control unit 202.然后，在步骤S706中，如上所述，第一主机控制单元202执行与数字静止照相机52的认证处理，在认证处理之后，由无线直接打印功能单元103执行无线直接打印处理。 Then, in step S706, as described above, the first host control unit 202 performs the authentication process with the digital still camera 52, after the authentication processing, wireless direct printing process performed by a wireless direct print function unit 103.

[0061] 另一方面，如果步骤S704中的判断结果表示连接请求帧中存在的识别符是第二主机识别符，则过程进入步骤S707，在步骤S707中，主机仲裁单元204将连接请求帧传送至第二主机控制单元203。 [0061] On the other hand, if the judgment result in step S704 indicates that the connection request frame identifier is present in the second host identifier, the process proceeds to step S707, in step S707, the host arbitration unit 204 transmits the connection request frame to the second host control unit 203.然后，在步骤S708中，第二主机控制单元203与个人计算机21 — 起控制适配器功能单元102，并且多重控制站201用作数字静止照相机52的WUSB适配器。 Then, in step S708, the second host control unit 203 and the personal computer 21 - adapter function unit 102 functions as a control, and multiple control station 201 functions as a digital still camera 52 of WUSB adapter.

[0062] 上述操作使得多重控制站201可以适当地选择并执行用于直接打印模式或PC连接模式的操作，而无需用户对多重控制站201执行任何特定操作。 [0062] The above-described operation such that the multiple control station 201 can be appropriately selected and performed an operation for direct printing mode or the PC connection mode, without requiring the user to perform any particular operation on the multiple control station 201.

[0063] 第二实施例 [0063] Second Embodiment

[0064] 接着，将参考附图详细说明根据本发明的第二实施例。 [0064] Next, with reference to the drawings in detail a second embodiment of the present invention will be described.

[0065] 注意，根据第二实施例的多重控制站201的内部结构与图1中示出并在第一实施例中说明的内部结构相同，因此，这里省略对其的说明。 [0065] Note that, the same is shown and described in the first embodiment, an internal configuration of multiple control station 201 according to a second embodiment of the internal structure of FIG 1, therefore, description thereof is omitted here.

[0066] 图5是示出根据本发明第二实施例的系统结构的示例的图。 [0066] FIG. 5 is a diagram showing an example of a system configuration of a second embodiment of the present invention.如图5中所示出，第二实施例的系统包括多重控制站201、个人计算机21、数字静止照相机52和WUSB硬盘（下文中简称为“硬盘”）206。 It is shown in Figure 5, the system of the second embodiment including multiple control station 201, the personal computer 21, the digital still camera 52 and a WUSB hard disk (hereinafter simply referred to as "disk") 206.将硬盘206连接到个人计算机21，作为个人计算机21的外围装置。 206 is connected to the hard disk 21, a personal computer as a peripheral device of a personal computer 21.因此，硬盘206通过用作适配器的多重控制站201将数据传送到个人计算机21/从个人计算机21传送数据。 Thus, the hard drive 206 201 transferred to the personal computer 21 transmits the data 21 to / from the personal computer through a data adapter as multiple control station.此外，假定当开始系统的操作序列时，数字静止照相机52没有运行， 意味着仅将硬盘206连接到多重控制站201。 Further, assume that the sequence of operations when the system is started, the digital still camera 52 is not running, meaning that only the hard disk 201 connected to the multiple control station 206.

[0067] 图6是示出根据本发明第二实施例的操作序列的图。 [0067] FIG. 6 is a diagram showing the operation sequence of the second embodiment of the present invention.第一主机控制单元202以循环的方式重复发送第一广播帧。 First host control unit 202 repeatedly transmits a cyclic manner a first broadcast frame.在第一广播帧中存在用于将多重控制站201识别为无线直接打印主机的第一主机识别符。 Present in the first broadcast frame for multiple control station 201 is identified as a first host identifier of the host wireless direct printing.然而，当开始该操作序列时，数字静止照相机52还未连接到多重控制站201，因此，不存在用作对第一广播帧的响应的无线帧。 However, when starting the operation sequence, the digital still camera 52 is not yet connected to the multiple control station 201, and therefore, the radio frame is used as a response to the first broadcast frame does not exist.

[0068] 类似地，第二主机控制单元203以循环的方式重复发送第二广播帧。 [0068] Similarly, the second host control unit 203 repeatedly transmits a cyclic manner a second broadcast frame.在第二广播帧中存在用于将个人计算机21识别为主机的第二主机识别符。 Present in the second broadcast frame for the personal computer 21 to a second host identifier identifying the host.因为硬盘206当前连接到个人计算机21，在第二广播帧内指定的时隙中，根据WUSB协议在个人计算机21和硬盘206 之间传送数据。 Because 21, a second broadcast frame in a specified time slot to transmit data between the personal computer 21 and a personal computer hard disk 206, according to WUSB hard disk 206 is currently connected to the protocol.这里，假定在图6所示的序列开始之前，已经完成了硬盘206和个人计算机21之间的认证处理。 Here, it is assumed that before the start sequence shown in FIG. 6 has completed the authentication process between the hard disk 206 and the personal computer 21.此外，存在两种情况：将数据从个人计算机21传送到硬盘206的情况； 以及将数据从硬盘206传送到个人计算机21的情况。 In addition, there are two cases: data transfer from the personal computer 21 to the hard case 206; and 206 to transfer data from the hard disk 21 of the personal computer.

[0069] 在这种状态下，如果随后在无线直接打印模式下启动数字静止照相机52，则数字静止照相机52接收正由多重控制站201重复发送的第一广播帧和第二广播帧。 [0069] In this state, if the digital still camera 52 is then started in a wireless direct printing mode, the digital still camera 52 receives the first broadcast frame and the second broadcast frame being repeatedly transmitted by the multiple control station 201.然后，数字静止照相机52检测在各广播帧中存在的第一主机识别符和第二主机识别符。 Then, the digital still camera 52 detects the presence in each broadcast frame in a first host identifier and the second host identifier.

[0070] 因为在无线直接打印模式下启动数字静止照相机52，因此数字静止照相机52选择指定无线直接打印主机的第一主机识别符，并利用连接请求帧对第一广播帧进行响应。 [0070] Since the digital still camera start in a wireless direct print mode 52, the digital still camera 52 selects the designated wireless direct printing host a first host identifier, and using the connection request frame in response to the first broadcast frame.在连接请求帧中存在第一主机识别符，因此当多重控制站201接收到该连接请求帧时，位于多重控制站201内的主机仲裁单元204从UWB无线单元104取得该连接请求帧。 There is a first host identifier in the connection request frame, and therefore when the multiple control station 201 receives the connection request frame, the host arbitration unit located within the multi-station 201,204 acquires the connection request frame from the UWB wireless unit 104.然后， 主机仲裁单元204分析该帧的细节，由此检测到在该帧中存在第一主机识别符，并将连接请求帧传送到第一主机控制单元202。 Then, the host arbitration unit 204 analyzes details of the frame, thereby detecting the presence of a first host identifier in the frame, and transmits the connection request frame to the first host control unit 202.

[0071] 此后，第一主机控制单元202基于WUSB主机协议，进行与数字静止照相机52的认证处理，并且最终完成了数字静止照相机52和多重控制站201之间的连接。 [0071] Thereafter, the first host control unit 202 based on the WUSB host protocol, authentication process with the digital still camera 52, and finally completed the connection between the digital still camera 52 and the multiple control station 201.然后，数字静止照相机52能够执行无线直接打印。 Then, the digital still camera 52 can perform wireless direct printing.

[0072] 接着，第一主机控制单元202通知连接检测单元205数字静止照相机52已经连接以进行无线直接打印操作。 [0072] Next, the first host control unit 202 notifies the connection detection unit 205 a digital still camera 52 has been connected for wireless direct printing operation.然后，连接检测单元205指示打印功能选择单元105断开迄今逻辑连接到打印功能单元107的USB接口单元106。 Then, the connection detection unit 205 instructs the printing function selection unit 105 to disconnect the logical connection date print function unit 107 of the USB interface unit 106.连接检测单元205进一步指示打印功能选择单元105将无线直接打印功能单元103连接到打印功能单元107。 Connection detection unit 205 further instructs the print function selection unit 105 to the print function unit 103 is connected to wireless direct printing function unit 107.借此，基于无线直接打印功能单元103的控制，将打印功能单元107连接到数字静止照相机52，从而使得能够打印来自数字静止照相机52的照片。 Accordingly, the control of the wireless direct print function unit 103, the print function unit 107 is connected to the digital still camera 52, so that the photographs can be printed from the digital still camera 52.

[0073] 第二实施例的特征在于即使将第一主机控制单元202连接到数字静止照相机52 以实现无线直接打印功能，也可以保持第二主机控制单元203和硬盘206之间的无线连接。 [0073] The second embodiment is characterized in that even if the first host control unit 202 is connected to the digital still camera 52 to realize wireless direct printing function can be maintained between the wireless control unit 203 and the second host 206 connected to a hard disk.换句话说，因为第一主机控制单元202和第二主机控制单元203通过主机仲裁单元204以时分方案共享UWB无线单元104，因此第一主机控制单元202和第二主机控制单元203能够作为两个独立主机工作。 In other words, since the first host control unit 202 and the second host control unit 204 to 203 time-division scheme shared UWB wireless unit 104 via the host arbitration unit, the first host control unit 202 and the second host control unit 203 can be used as two independent master operation.

[0074] 如图6中所示，数字静止照相机52在第一广播帧中指定的时隙期间持续地与多重控制站201内的第一主机控制单元202进行通信。 [0074] As shown in FIG continuously with the first multiple hosts in the control station 201 during a communication control unit 2026 of the digital still camera 52 in the designated time slot in the first broadcast frame.此时，通过由主机仲裁单元204进行的处理，在数字静止照相机52和无线直接打印功能单元103之间交换拍摄数据、控制信息等的无线帧。 In this case, by the processing performed by the host arbitration unit 204, between the digital still camera 52 and the wireless direct printing function unit 103 to exchange data imaging, a radio frame control information.

[0075] 另一方面，硬盘206在第二广播帧中指定的时隙期间持续地与多重控制站201内的第二主机控制单元203进行通信。 [0075] On the other hand, continuously with the second host control unit within the multiple control station 201 communicate with the hard disk 206 designated period 203 in the second time slot broadcast frame.此时，通过由主机仲裁单元204进行的处理，在硬盘206和适配器功能单元102之间交换从硬盘206读出的数据、写入硬盘206的数据、控制信息等的无线帧。 In this case, by the processing performed by the host arbitration unit 204, between the hard disk 206 and the adapter function unit 102 to exchange data read out from the hard disk 206, the hard disk 206 to write data, the control information of a radio frame.

[0076] 如迄今所述，根据第二实施例，即使连接到数字静止照相机52的多重控制站201 当前正在打印照片，多重控制站201也可以继续作为适配器工作。 [0076] As described so far, according to the second embodiment, even if the digital still camera 52 is connected to the multiple control station 201 is currently printing photographs, multiple control station 201 may continue to work as an adapter.

[0077] 注意，可以将本发明应用于包括多个装置（例如，主计算机、接口装置、读取器、打印机等）的系统，或可以应用于包括单个装置（例如，复印机、传真机等）的设备。 [0077] Note that the present invention can be applied to a system comprising a plurality of devices (e.g., host computer, interface device, reader, printer, etc.) or may be applied to a single device (e.g., a copying machine, a facsimile machine, etc.) device of.
